Blower Door Test in Riverside, NJ

How Is A Blower Door Test Conducted?

For accurate blower door test in Riverside, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.
